Question:

Estimate the mean free path of a N2 molecule in air at
(a) Sea level (P ≈ 100 kPa and T ≈ 290 K),
(b) The top of Mt. Everest (altitude = 8.8 km, P ≈ 50 kPa, and T ≈ 230 K), and
(c) An altitude of 30 km (P ≈ 1 kPa and T ≈ 230 K). For simplicity, assume that air is pure nitrogen gas. The diameter of a N2 molecule is approximately 0.3 nm.
